I think Stefan and Juri should chime in with their experience about
this, since as I've seen, they both want to replace some custom cursor
code with the new mode in their configuration.

I tried the patch with 'run-with-idle-timer',
and even the delay 0.1 is noticeable and causes
the feeling that Emacs became sluggish
and can't update the cursor immediately.

I think with 0.005 is most that fine, it's not immediate but also not
too lazy IMO.

Anyways the user can change the delay to 0.
